Conductivity Level Switch is a simple, low cost, point level measurement switch designed for level detection of conductive liquids having low densities, high viscosities, containing solid particles and to detect interface between non-conductive and conductive liquids. The probes work through the variation of the electrical resistance between the reference electrode and the level-control electrode. Conductivity level switches detect the level resistance when their electrodes are covered by the medium. If the tank is made of plastic, concrete, or any other nonconductive material, an additional electrode is required as a reference Conductivity Level Switches are available with stainless steel 316 electrodes as standard Suitable for many chemicals and aggressive media which are conductive in nature and dirty liquids, liquids with high solid content Construction available with both Solid probes & Suspended probes to suit fitting requirement It is a simple, low cost, point level controller designed for detecton of conductive liquids, having low densites, high viscosities, containing solid particles and interface between nonconductive and conductive liquids. CONSTRUCTION & OPERATION It comprises of a probe, wired to a level controller. The probe holds one common reference/common electrode and one or multiple “Control Electrodes” depending upon the number of levels to be controlled. All the electrodes are suitably insulated to avoid electrical bridging. The lengths of “Control Electrodes” correspond to the height of preset level points to be controlled and the length of the “reference/common Electrode” is kept slightly longer than the longest “Control Electrode”. If tank is conductive, it can be used as a reference/common electrode. Then number of control electrodes equals number of preset levels. Level controller houses sensing electronics consisting of power supply and signal conditoning circuit which provide a “Low AC Voltage” across mass and control electrodes. On liquid reaching preset level point electrical circuit gets completed - generating a signal which is amplified to actuate a relay, those potential free contacts are available for subsequent operations. On “Level Falling” the circuit breaks, deactivating the relay Additional Information: Production Capacity: 100 Delivery Time: WEEK Packaging Details: EXPORT WORTHY PAKING

NRG GLOBAL MAKE Displacer type level switches offers the industrial user a wide choice of alarm and control configuration. DLS works on a simple buoyancy principle and is well suited for simple or complex applications, such as forming surging liquids or agitated fluids, and usually costs less than other types of level switches. CONSTRUCTION & OPERATION Operation is based on simple buoyancy principle. As the liquid level rises and progressively immerses the displacer elements, the effective weight suspended on the spring reduces and the consequent length of the spring change is used to provide magnet movement and operate the switch. The spring movement causes the magnetic sleeve to attract a pivoted magnet actuating a switch mechanism located outside the barrier tube. Built-in limit stops, prevent over stroking under level surge conditions. FEATURES: • Wide choice of switching functions • Suitable for large tanks up to 15 meters • Site adjustable switch points • Customized for high temp, high pressure & vaccum applications. • Reliable performance in turbulent liquids even without still pipes. • Easy transportation of longer length switches. • Enclosure : Weather proof-IP-65 Ex-proof-Gr.

NRG GLOBAL INSTRUMENTS MAKE Glass Tube Variable Area Flow Meters (Rotameters) are intended for general in line and ByPass metering applications (i.e. for Gas & Liquid) where operating conditions are with the limitations of Glass metering tubes. These are the principle of Variable Area. The float moves freely up and down tapered borosilicate glass with fluid flow from bottom to top. The float takes up a position where buoyancy forces and the float weight are balanced in proportion to flow rate. The Vertical position of the float as indicated by scale is the measure of the instantaneous flow rate. 2. Principal of Operation When fluid or gas flows through a taper tube containing a float, a pressure difference of P1 and P2 is created between upper and lower side of the float. The float moves upwards by a force obtained by multiplying the pressure differential by the maximum cross-sectional area of the float. Due to taper tube, as the float moves upwards, the fluid passing area increases as a result of which the differential pressure decreases. Upward movement of float stops when the dead load is dynamically balanced by the differential pressure.

This is micro-processor based Donnelly Chute level Transmitter with isolated o/p (4-20 mA), 10nos digital optical o/p and 2 relay control .The instrument is field programmable and user friendly. In this Instrument user can set sensor sensitivity, sensor level selection, sample delay time and relay set point etc. The user can set level 2-10 then instrument automatically tunes for o/p 4-20 mA and display 0-100%. The instrument has five settable parameters like rL1,rL2,snt,trl,Lst. The Instrument reads input level in sequence 1 to 10 if misplaced any level then it will not show above levels.
